Among these features, antitumor activity has become more important in recent years and it still demands more investigations to address the underlying mechanisms. Purpose: This current study was conducted to evaluate the anti-proliferative effect of Ferula assa-foetida on PC12 and MCF7 cells as well as examining its mechanisms. Materials and Methods: Cells were cultured in DMEM medium with 10% fetal bovine serum, 100 units/ml penicillin, and 100 µg/ml streptomycin. Cells incubated with different concentrations of the ethanolic extract of Ferula assa-foetida. Notably, cytotoxicity and apoptosis assay were measured by MTT and PI staining, respectively. Results: The MTT results showed that the ethanolic extract of Ferula assa-foetida in concentrations of 10, 7, 5, and 2.5 μM on both PC12 and MCF7 cells had a significant effect in cell viability and apoptosis induction in comparison to control group. Conclusion: In this study, it was determined that Ferula assa-fetida through the induction of apoptosis prevented the growth of PC12 and MCF7 cells and made a reduction in cell viability with different concentrations in a time- and dose-dependent manner. However, more studies are needed to reveal the mechanisms of Ferula assa-foetida’s extract in apoptosis induction.","PeriodicalId":73426,"journal":{"name":"International journal of biomedical engineering and clinical science","volume":"71 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2020-10-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79989534","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It is one of the five Leading causes of maternal death in the developing world. Moreover, in developing country, abortion is the major cause of maternal mortality, which in Ethiopia safe abortion accounts 60% considering the huge number of maternal deaths due to abortion. The aim of this study is to Assessment of KAP Women of Reproductive Age Group towards Abortion Care at Gambella health facilities. An institutional based cross-sectional study will be conducted at 4 Health facilities in Gambella town from August 15 to September 30, 2019. A total of 412 pregnant women will be selected by systematic random sampling technique. Data will be coded and entered into Epi-info version 3.1 and exported to SPSS V-20 for cleaning and analysis. At bivariate logistic regression analysis, independent variables with cut off P-value<0.25 was included. In the multivariable binary logistic regression analyses were used to assess the independent effect of various explanatory variables on the dependent and to control potential confounder. P values <0.05 were considered to identify the significant factors associated with the dependent variable. Out of 422 sampled women of reproductive age group (15-49 years of age), 412 were interviewed making up a response rate of 97.6%. The majority of 39.1% participants had knowledge about legal abortion service and 69.5% of women in reproductive age group had inadequate knowledge towards safe abortion and who think about abortion, 174 (42.2%) were said that it is Sin against God, 52 (12.5%) were said that it is good, 67 (16.2%) were said that it is harm full practice and 40 (9.6%) were they don’t knew. Attitude towards safe abortion about, One hundred Eight two (29.9%) women of reproductive age group have positive attitude towards safe abortion to be legal and accessible under any circumstance. The majority of 322 (78.1%), of them knew at least one type of abortion complication. From the total respondents 405 (98.3%) of them had sexual intercourse at least once. Only 66 (16.3%) of respondents had induced abortion before. Conclusion and Recommendation: More than 30.5%, 29.9% of the respondents were inadequate knowledge and lacking knowledge and had negative attitude towards induced abortion respectively.

A low temperature not only reduces respiration rate, but also water loss through transpiration, nutritional loss, postharvest decay and ethylene production. Laboratory studies were conducted on the water holding capacity of the selected walling materials after socking them in water overnight. Scoria, charcoal and filla (single strap and double strap) were used for the study at different times. A water holding capacity of up to 122.72% was recorded in 24 hours of soaking in the case of the filla walling material. Similar studies were conducted on other walling materials like scoria and charcoal. Tests were conducted under no load and loaded conditions. Longer shelf life is manifested in the scoria and charcoal storage structures, attributed to higher humidity, lower temperature, less color change indicates lower rate of spoilage. Three creates of cleaned potato were stored in the potato store and in the laboratory as a control. Data on weight loss, spoilage and sprouting were taken for 50 days for the ware potato. Then the test was extended for another two months to assess the quality of the structure as a seed potato store. The degree of spoilage was lower compared to the control, but the difference was not significant in the ware potato. As a seed store, the number of sprouts, especially higher number of potatoes with greater than 5 sprouts was recorded in the control, which was also significant. From this preliminary result the structure could be a better choice as a potato seed store.","PeriodicalId":73426,"journal":{"name":"International journal of biomedical engineering and clinical science","volume":"46 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-11-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75068073","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The review was conducted with the aim of assessing the rational use of veterinary antimicrobials. Veterinary drugs are used in livestock sector either rationally or irrationally. Rational use of veterinary drugs means sick animals receive medications appropriate to their clinical needs, in doses that meet their own individual requirements, for an adequate period, and at the lowest cost. Whereas irrational drug use are characterized by over prescription, omission, the use of inappropriate dosage, incorrect duration, misuse of drug, take unnecessary risk, over use /frequent use of drugs and not stick with withdrawal period of a drug. The review indicates veterinary drugs used irrationally due to lack of knowledgeable of healthcare providers, lack of treatment guidelines, essential drug lists and national formularies, lack of diagnostic support services such as laboratory services, self-medication and purchasing of antibiotics directly from pharmacies, street vendors or markets and inadequate supply of veterinary drugs. Irrational use of drugs leads to antimicrobial resistance which is the current global health threat to animals and human being. Hence, veterinary drugs, especially, antimicrobial agents should be prudently used, improve availability of key essential drugs on stock through good drug supply management to reduce misuse of drugs and therapeutic failure, keep the withdrawal period to safeguard the public as well the livestock from drug residual effects and development of antimicrobial resistance are recommended.","PeriodicalId":73426,"journal":{"name":"International journal of biomedical engineering and clinical science","volume":"26 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-11-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74666627","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The manual analysis of clinical images lets to both repetitive tasks and management of huge amounts of data. This is tedious and times consuming for laboratory technicians. Inevitably, it is also prone to human errors. Our objective in this work is to contribute to the automation of the analysis of microscopic images of stools using Distance Regularized Level Set Evolution automatically initialized by Hough transform. Method: We firstly converted the microscopic images to edge maps using canny algorithm. Next, we located the parasite through circular Hough transform and draw circles around them. Those circles stand as initial contours of DRLSE. The contours evolve until they fit the boundaries of the parasites. The final extraction is performed using a complementary method based on the signed distance character of the level set function. Results: The Distance Regularized Level Set Evolution has been automatically initialized. We applied our method to the detection of intestinal parasites in microscopic images. Experimental results show accurate, efficient and less time consuming of our scheme compared to others recently proposed in the literature. Conclusion: This is a notable contribution to the automation of stools examination in the medical laboratories. In forthcoming works, we plan to include this segmentation process in an expert system of parasitic diseases diagnosis.","PeriodicalId":73426,"journal":{"name":"International journal of biomedical engineering and clinical science","volume":"37 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-10-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85948354","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The leaves of P. dodecandra were collected in January 2017 at Yakoma city, Nord-Ubangi, DRC. Three bacterial strains namely Staphylococcus aureus ATCC 25923, Escherichia coli ATCC 8739 and Pseudomonas aeroginosa ATCC 9027 were used for the assessment of the antibacterial activity. The qualitative and quantitative phytochemical screening were used for compound identification. The antioxidant activity was assessed using ABTS and DPPH scavenging tests while the antibacterial activity was performed using the diffusion method. The findings show that leaves of this plant are rich in flavonoids, anthocyanins, terpenoids and irrioids. The inhibitory concentration 50 (IC50) values obtained in the ATBS test are lower than those of the DPPH test. The antibacterial activity of this plant was low against the three strains used.
